Tension City

Let's start with President Bush himself. How is he holding up?

"He can barely stand, he's about to drop on the spot," Bush said, with several of his trademark chuckles, when Matt Lauer asked on the Today Show yesterday morning.

"He's doing great. He's got big, broad shoulders," insisted the first lady.

But maybe Bush was closer to the truth than his wife. Washington Post columnist Dana Milbank 's close inspection of Bush's body language in the video of the interview exposed any number of signs of strain -- including blinking and twitching,

"Only the president's closest friends and family know (if anybody does) what he's really thinking these days, during Katrina woes, Iraq violence, conservative anger over Harriet Miers, and legal trouble for Bush's top political aide and two congressional GOP leaders. Bush has not been viewed up close; as he took his eighth post-Katrina trip to the Gulf Coast yesterday, the press corps has accompanied him only once, because the White House says logistics won't permit it. Even the interview on the 'Today' show was labeled 'closed press.'.

"But this much could be seen watching the tape of NBC's broadcast during Bush's 14-minute pre-sunrise interview, in which he stood unprotected by the usual lectern. The president was a blur of blinks, taps, jiggles, pivots and shifts. Bush has always been an active man, but standing with Lauer and the serene, steady first lady, he had the body language of a man wishing urgently to be elsewhere.

"The fidgeting clearly corresponded to the questioning. When Lauer asked if Bush, after a slow response to Katrina, was 'trying to get a second chance to make a good first impression,' Bush blinked 24 times in his answer. When asked why Gulf Coast residents would have to pay back funds but Iraqis would not, Bush blinked 23 times and hitched his trousers up by the belt.

When the questioning turned to Miers, Bush blinked 37 times in a single answer -- along with a lick of the lips, three weight shifts and some serious foot jiggling."

Milbank also touches on Bush's habit of making inappropriate facial expressions. At one point, he writes, Bush "seemed to lose control of the timing. He smiled after observing that Iraqis are 'paying a serious price' because of terrorism."

And Milbank doesn't even mention the tic that has been the subject of intense speculation in the blogosphere for several months: Bush's bizarre, shifting lower jaw movement that increasingly punctuates the ends of his sentences.

Harry Shearer first wrote about it three months ago in the Huffington Post blog, right after Bush's nomination of John Roberts to the Supreme Court.

The strange jaw movement was amply on display just last week during Bush's press conference, as seen in this compilation video .

Back in July, The New York Daily News's Lloyd Grove wrote that he asked press secretary Scott McClellan if Bush has a bite issue -- but apparently McClellan never responded.

So who knows what it could be?
